JONSON, or snnrrrnn, wesninerolv BUILDING wnvnow FRAME Application filed. April 17,

My invention relates to the art of building win-dow frames.

Objections to window frames, as heretofore commonly designed and constructed, obtain in the following respects: First, since the window frame ordinarily makes provision for the opening and closing of a window member, many joints are found in its construction, and as the window frame is exposed to heat of summer and to rain, the opening of the joints and permitting of the rain to enter is very difficult to guard against. The rain in particular against the window pane follows down along the blind stop members and onto the main sill, from which, if it runs inside, it stains the plaster.

Again, the opening of the joints and the construction of the frame otherwise, as heretofore designed, does not ordinarily guard sufficiently against the entering of wind.

Furthermore, the window frame members have been relatively expensive tomanufacture in view of the size of the materials entering into their construction. In the lumberyard, there are certain sizes of materials that are standard and often result as a byproduce in the manufacture of other types of lumber. For example, there is a great deal of 1 X 4: material, this being the size ordinarily employed for the manufacture of flooring. Flooring requires that the grain be straight as opposed to slashed grain.

Slashed grain is objectionable particularly.

for flooring, since it is subject to splintering. Therefore, there devclopsja' great deal of 1 X4 material by way of culling out, which is not suitable for flooring, that must be used in such other lines of manufacture, where the straight grain is not so important, as in 40 flooring, wherethe continued direct wearing on the surface especially tends to develop splintering. Therefore, the cost of manufacture of an article, such as a win-dow frame, obviously may be greatly reduced if it may be so designed as to employ said relatively' inexpensive IX 4' material. Moreover, the main sill of the ordinary window frame is a very substantial heavy member, being made of 2 x 8 material, which it is my purpose to eliminate, and at the same time to provide 192s. seal No. 102,614.

a window which will operate with greater satisfaction. 7

Also, as window frames are commonly designed and constructed, there is not provided a window weight recess free and clear of plaster, which protrudes through the lath,the lath forming one wall of the weight recess. foreover, the applying of the lath tends to bow inwardly the pulley stiles, so that the opening and closing of the window member is often very difficult, because the guide-ways have been deformed in the manner described. Thus is made clear the importance of avoiding direct contact between the lath and the pulley stiles, and the forming of a window frame which is ofsuch strength that it will not be deformed, and interference with the movement of the windows is thusavoided.

A primary object of my invention is to provide a window frame, which will overcome all these objections, which will prevent, water fromleaking through to the inside and staining the plaster, and which will also be windproof. Furthermore, a primary object of my invention is to provide a window frame which will be inexpensive to manufacture in View of the employment of materials which may be readily bought on the market as standard product and of a grade much less expensive, as herein explained. Also, an object of my invention is to provide a window frame which employs a 2 X 4 material for the main sill. Still another primary object of my invention is to provide a much stronger window frame than has heretofore been designed and constructed, and to provide a window frame which will have a shoulder formed therein as an abutting means for window screens and weather window storm sash.

The above mentioned general objects of'my invention, together with others inherent in the same, are attained by the device illustrated in the following drawings, the same being merely preferred exemplary forms of em-- 95 bodiment of myinvention, throughout which drawings like reference numerals indicate like parts: Figure 1 is a front view in perspective of 'awinolow frame embodying my invention,

' deflect any water that-might get past the with a fragment broken away in one corner;

Fig. 2 is a perspective view of an enlarged corner detail with parts broken away, and associated parts of the building;

Fig. 3 is a fragmentary sectional View from the rear side of the frame embodying my invention, and associated building parts;

Fig. 4 is a view in perspective of the'sill member;

Fig. 5 is a fragmentary view' in perspective and in section on dotted line 5, 5 of Fig.1; and

Fig. 6 is a fragmentary view in perspective of a modified form of one detail of the invention, showing the sub-sill dadoed to receive the sides.

The main sill 7 is provided with a raised shoulder 8 on the rear upper side and a groove 9011 the front portion of the underside, into which the siding 10 may extend, said main sill also having endextensions 11. This main sill'is preferably formed from ,2 X i stock,

instead of the ordinary 2" X 8" base which constitutes the sill. p

The sub-sill 12, preferably formed from 1 X 6 stock, is disposed upon the main sill.,

Against the end of the sub-sill are disposed the side members, jambs or pulley stile 13, which may be .dadoed to receive the sub-sill .2, or, as shown in Fig. 6, the sub-sill may be dadoedto receive the sides. Blind stop 14 abutsagainst the side memberliif Outside casing 15 and inside blind casing or lining 16 form the weight box recess 17, the upper side of said recess being formed by the studding of the building 18. Outside head linin 19 and insi le lining 20, togetherwith the bottom inside lining 21, are members whose po sitionis indicated in the drawings. If desired, a moulding 22 may be added. WVindow dividing member 23 serves to provide two guide ways for the lateral edges of the window' sash. A removable cover 24, held in position by screws 25, affords ready access to weight well 17. The position of the lath 26 and the plaster 27 is such that it does not 1nterfere with the weight well 17. The stool 28 and the apron 29 completethe dressing of the window on the inside.

In themodified form, Fig. 6, the sub-sill 30 is dadoed to receive the side members 31, i.- e., the jambs orpulley-stile.

The mode of operation of a device embodys ing my invention is as follows: 7

It is manifest that rain beating against the window panes and running down between V the blind stop 14 andthe'side -members 13.

would beprevented from reaching the plaster underthe window on the inside of the house by reason of the shoulder 8 on the main sill 7. This shoulder would tend-to joint-form d bythe blind stop d the edg portions of the side member 13. ltrwillibe remembered tha the e-joii s may e'opened moreer ess by -theshrinking ofthe oo consequent upon the drying effect of the heat of summer after the rain and storm of winter. Since the siding 10 fits in the sillmember 8, the window frame is particularly well adapted to exclude wind and storm, and in view of the use of the combination of the sill and sub-Sill, and otherwise utilizing 1 X 4 stock, which the peculiar construction of the window embodying my invention renders possible, a window frame is provided which is characterized. by its economy of manufacture as well as by its strength. The arrangement of the parts insures the elimination of all water and provides for keeping the plaster and lath portion back from the weight well, so that the applying of the lath and plaster cannot crowd'the jambs out of .line, and cause them to bind on the window sash, which renders the sashordinarily very diflicult, if not impossible, to operate. Also,

the well sides are 'free from protruding masses of plaster. Since the main sill has the extensions 11 which extend through, this prevents any possible leakage from coming in contact with the plaster. Providing the outside back band 19 renders it unnecessary to have; any flashing. Adding the inside casing 16 renders the frameparticularly strong, and keeping the plaster at a distance from the side members or pulley stile prevents the frame from beingdistorted, which renders it difficult, if not impossible, to move the sashnp and down. Adding the'inside lining member 21makes the frame sound and weather-proof, and makes ample surface for the inside apron. Particularly are the joints adapted to be very tight inview of the fact that they are accurately machined.

Obviously, changes may be made in the form, dimensions and arrangement of the parts of my invention, without departing from the principle thereof, the above setting forth only preferred forms ofjembodiment.

I claim: 1. In a building window frame, the combination of a pulley stile on'eachside; a main sill-extending beneath and beyond the bottom of said pulley stiles, said sill having a raised shoulder on the rear upper side,.said upper side sloping downwardly outwardly; and a sub-sill disposed as respectsitsfront end portion in partial overlapping position on top of said main sill, the raised shoulder of which main sill extendsup into said sub-sill, andsaidsub-sillbeing entirely disposed be-. tween said pulley stiles, whereby a portion of said mainsill with the raised shoulder extends laterally beyond said pulley stiles, so that water is prevented from entering rearwardly of said shoulder on that portion":

s llat endingb neath-andh yenclthebottonr of said pulley stiles, said sill having a raised shoulder on the rear upper side, said upper side sloping downwardly outwardly; a subsill disposed as respects its front end portion in partial overlappingposition on top of said main sill, the raised shoulder of which main sill extends up into said sub-sill, and said sub-sill being entirely disposed between said pulley stiles, whereby a portion of said main sill with the raised shoulder extends laterally beyond said pulley stiles, so that water is prevented from entering rearwardly of said shoulder 011 that portion of the main sill disposed laterally of said pulley stiles; a blind stop on each side of the frame against which said pulley stile abuts as respects its front edge; outside side casing members and head casing member; and inside side lining members against which said pulley stile abuts, a head inside lining member, and a bottom inside lining member, by reason of which inside lining members said frame is strengthened and an enclosed weight pulley pocket is provided.

In Witness whereof, I hereunto subscribe my name this 30th day of March, 1926.
